To aZZ whom it may con/cern,.-

Be it known that I, VICTOR M. SUMMA, a

citizen of the United States, residing at St.

Louis city and State of Missouri, have i11- vented -new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to dump-cars, and is improvement upon the 1 and arrangement of.parts hereinafter more fully described, illustrated, and claimed.

, In the accompanying drawings, Figure 1 is an end viewv of a dump-car embodying the present invention. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 'is a cross-section through the car, showing in full lines the several doors o r sections thereof set to form a flat-car and showing'in dotted lines the position the center doors assume to form a side-dump car. Fig. 4 is a section similar to Fig. 3, showing the several doors or sections adjusted to constitute a centerdump car. Fig. 5 is a detail cross-section through one of the side stakes or vertical braces in' line with the longitudinal stiiener.

Fig. 6 is a detail vertical section showing a modified connection between the side sills and cross-sills. Fig. 7 is a detail section on l the line 7 7 of Fig. 6.

The car in its general construction embodies the end cross-sills 1 vand a series of 1n- ,termediate cross-sills or diaphragms 2, which lare all connected by center sills 3, extending longitudinally of the car and beneatn the plane of the bottom thereof. The car also comprises the side girders 4 and the ends 5, which form the box or body of the car.

' The floor 'of the car is composed of several sections or doors, 6 and 7 designating the center doors, and 8 the lower sectionsof the side doors, while'9 desi nates the upper sections of the side doors, t e latter being hinged to the side girders, as shown in Figs. 3 and 4.

the olii;

Secured to the upperedge lof each of the center sills 3 isa tubular butt or knuckle 10,

upper edge thereof into semicylindrical form, as shown', to form the pivot or knuckle of the hinge.` The door 6 is provided at one edge with a plurality of straps 11, which are bent to encircle the tubular butts 10 and which constitute the knuckles of thedoor, forming -part of the "hinge-joint. The door 6 also com rises one or more downwardly-extending and an end cross-piece 13 of,v a' reverselyflanged angle-iron, which when the door 6 is 14,- proj ectin other .center 3, the said door 7 being hingedin the same manner as the door 6. The door 7 is smaller than the door 6 and is provided at its free edge and on its upper side from the uppervface of the the last-named door is lowered to the osidoor 6 is shown as resting on said stop-cleat.

The cross-sills or center separators are rovided with horizontal slots 16,',` jwhic is arranged a laterally-,sliding rod or shaft 17, -which forms a sup ort 'for the door 6, as shown in Figs. 3 an bodily laterally by means of a plurality of chains 18, which are connected to and naled in the cross-sills, said upon its' projectingsquared end 21`. `Upon wheel A22, adapted to be engaged and held by a dog 23, having an operating-handle 24 connected therewith. The shaft 2Q is further provided With one or more cams. 25, which operate against the lower side of the door7 as the door 6 is drawntoward the cleat 15 beneath the free edge ofthe doorI 6 in the manner-illustrated in Fig. 4. This serves to position the center doors in readilthe bottom o the car.

-The side doors 8 are hinged to the tubular butts or knuckles 10 in the same manner as the center doors 6 and 7 and are stiffened at theirouter ends by the reversely-flanged consisting of a sheet-metal plate having the` above the sill 3 rolledv with a flanged stop-cleat 15, which 'forms a seat or'rest for the larger center door 6 when 4. This shaft is moveddoor 7, said cams serving to thrust thestopness for dumping the load centrallythrough anges 12- disposed horizontally to form a section'of the car-floor rests upon the upper ends of Hanges oor 7, as clearly` shown in Fig.

tion shown in Fig. 4, wherethe edgeof the wound upon pulleys 19 on a shaft 20, eX- tending longitudinally of the-car andi jour-f shaft being adapted to receive a suitable operating-crank i l the projecting end of the shaft 20 is a ratchet- IOC ' 33 fat the side of the car.

angle-irons 26, while they are provided on theirbottoms wi-th one or more downwardlyextendingilanges 27, adapted to rest directly upon rolling `and traveling shafts 28. Two of these shafts .are employed extending lengthwise of the car-bottom at opposite sides, and said shafts are movablelengthwis'eof guide-slots 29, formed in the cross-sills, as shown. 'lhe major portion of each slot is inclined, as shown, while the upper end thereof is extended for a short distance horizontally, as shown at 30, so that when' the shaft 28 is in the horizontal portion of the slot it forms a irm support for the superimposed door, the flanges 27 of which rest directly on said shaft. By reason of the horizontal disposition ofthe portion 30 of the slot there is no tendency of the shaft 28 tp recede down the inclined portion of the s ot. A

Each of the shafts 28 is provided -with one or more grooved pulleys 31 and has connected Athereto a corresponding number of chains 32, which Wrap around the pulleys as the shaft is rotated, the opposite ends of the 'chains being connected to stationary eyes Each shaft 28 is provided with a squared extremity. `34, adapted to receive a suitable operatingcrank, and is further provided with a ratchetwheel 35, adapted to be engagedby a dog 36, having an operating lever-arm 37, said dog being pivotally mounted on adog-carrier 38, which travels back and forth on a track or guide 39, secured to the outer face of the end plate 4() of the car, as shown in Fig. 1. Each'shaft 28 is further provided at i' rotate -to move in a'direction which will effect a 'suitable points with s ur-pinions 41, which engage With short rac s 42 under the horizontal portions of the slots 30, secured to the cross-sills, the geared arrangement shown and described serving to keep the shaft in4 true longitudinal alinement and also insuring the movement of the shaft from the hori- 'zontal portion of the guide-slots to the iiiclined: ortions 29 thereof when said shaft is d). by theoperating-crank and caused lowering or dropping of the side doorsections 8 when .the car is -used as a side UnderftheA arrangement shown in Fig. '4,

in which the car is used-as a center dumper,

vvthe side door-sections 8 are raised at their outer edges, as shown in said Fig. 4, so that the projecting ends thereof iit into grooves or rabbets 43 in the free edges of the upper sections 9 of the side doors, this arrangement being clearly shown 'in Fig. 4, wherein it will also beseen that vthe upper side doorsections 9 restag'ainst rojecting steps 44, secured to the sides orA ongitudinal girders of the car.

In adjusting the pants. to forma sideq dump car the center doors -6 and 7 areelevated, as shown in dotted .lines in Fig. 3, so

that the free edge of the smaller door 7 will rest in notches 45in the flanges 12 ofthe sides of the car-bottom ready to'be dumped when the side door-sections 8 are dropped.

Hitherto the longitudinal girders or sides of the car-body have been composed of upper and lower angle-irons 46 and 47, respectively, and a connecting web or plate 48 of sheet`r iron, and the practice has been to make the upper angle-iron or top sill 46considerably heavier than the lower angleirons or bottom sill 47. I purpose to make the upper and lower angle-sills 46 and 47 of approximately or exactly the same size and to em loy side stakes or vertical .braces 49, extendli the upper sill 46 to the lower sill 47, said side stakes being formed out of reversely-fianged angle-irons and all connected. at the lupper side by a longitudinal sti'H'ener or brace 50,

located at the top of the stakes and` in line with the upper sill or angle-iron 46 and securely bolted or riveted thereto, as shown at 51. The construction just described imparts much greater strength to the car sides and ng from' enables them the moreeffectively to resist the lateral strain thrown thereon by the load and at the same time effects a material savf ing in weight and cost of manufacture.

The ends 5 of the carare bracedby horizontally-extending reversely-disposed angle-A irons 52, vhaving their endsbent and secured to the slide-plates of the car, extending y *lengthwise of the ends and secured together by bolts or rivets 53, around which are placed spacin sleeves or thimbles 54, which are ini c lo;

osed y thev channel-irons, as shown `in Fig.

2. Each end is also provided with an intermediate longitudinal/brace 55, secured'to they outer side thereof and held by rivets and spacing-sleeves similar Ato 53 and 54, above referred to.

The oorof the car further comprises the transverse doors or sections 56, which are hinged thereto at 57 and provided attheir IJO free edges with angle-irons 58, adapted torest upon-other angle-irons 59,-secured to the stationary section Fig. 2. to the dotted-line position shown in the same figure, in which posi-tion they each form a support for thelower end of one of the end plates 5, which is provided at its up er edge withan angle-iron 60 and a hinge-rod ends of which rest on the top of the car sides, while the lo'wer free edge of the end plate is provided with an angle-iron 62, one flange of which is adapted to hook over and engage the upper edge of the plate or floor-section', as shownin the dotted-line position in Fig. 2. J The ends of the rod 61 are adapted to slide on tapv of the sides and are held beneath straps 61, the- 68, which also serve to limit the sliding movement of the end plate 5, as clearly shown in Fig. 2, so that when the end plate 5 is swung upward tothe dotted-line position of Fig. 2 the angle-iron 62 will rest on top of the floorsection 56 when standing vertically.

Instead of extending the sides downward outside of the ends of the cross-sills, as shown in Fig. 3, the cross-sills may extend outward beneath the sides, as

shown in Figs. 6 and 7, so that the side sills cross-sills, in`which case metal ties or angleirons 64 are riveted to thevsides and crosssills, as shown in Figs. 6 and 7, in order to securely anchor said parts together. It will be noted that theflange 65 ofthe tie 64 is cut away from the top of the cross-sill 1 downward, thus enabling one flange to be riveted to the side and the other flange to be riveted to the cross-sill, all of which is clearly shown in Fig. 6.

From the foregoing description it will be seen that the car may be readily 'converted v'into any one of three types-a flat or gondola car, a center-dump car, or a side-dump. caralso that means are provided for securely holding the movable parts of the floor-secl tions or doors in their respective osition for adapting the car to its severa uses; furthermore, that effective means are. provided for adjusting the several parts and'supporting said parts firmly whenadjusted.
